Hi,
You can use fatigue typology rules to refine threshold on profiles and deliveries. All deliveries using this typology rule will execute the rule, but you decide, among the past and scheduled deliveries, which ones you want to count. For example, if your restriction is 'Label starts with Newsletter', the rule will be executed even if the delivery label starts with 'Promo'. It will count, over the selected sliding period, the number of deliveries whose label starts with 'Newsletter'.
Thanks, David
